I.Features Introduction

1.Fully electronic controlled, digital display system, direct display of main construction parameters such as rotating torque and push-pull force, which overcomes the disadvantage of conversion of pressure gauge used by traditional hdd drilling rig, and the operation is simple.
2.Multi working condition mode selection: select the corresponding operation mode for different geological conditions, with wide equipment adaptability and high work efficiency.
3.The torque of loading rods on the power head is equipped with overloading protection system and adopts electronic sensing, which has the advantages of rapid response, sensitivity and high reliability; Stepless adjustment of rotating torque to adapt to complex working conditions; The stepless adjustment of rotating torque adapts to complex working conditions. The floating main shaft of the power head reliably protects the drill pipe thread and improves the service life of the drill pipe.
4.The intelligent control system includes automatic idle speed, one key operation, integrated operation, cruise function, power head position judgment, automatic deceleration of front and rear positions of power head, impact reduction, automatic swing and guidance control system (optional function)
5.The mud flow can be adjusted steplessly in multiple stages, and the mudflow can be started and stopped automatically to save mud and reduce pollution
6.Equipped with rotating cab, wide vision of the whole machine, dual electronic control handle mode and wire controlled proportional walking system.The operation is comfortable, efficient and safe.
7.Optional more power head to double the pull back force of the power head to meet the special needs of customers
